SUMIO o KOTA United States Patent POURING SPOUT FOR BOTTLE Sumio Yokota, Gardena, Calif.

Application April 10, 1953, Serial No. 347,905

3 Claims. (Cl. 222-526) This invention relates to pouring spouts for bottles and more particularly to a detachable pouring spout for a bottle adapted to contain a viscid'substance, such as table syrup.

It is among the objects of the invention to provide an improved pouring spout which can be detachably mounted in the mouth of a bottle and moved outwardly of the bottle mouth when liquid is poured from the bottle to maintain the liquid out of contact with the mouth of the bottle; which has a sharp edge disposed outwardly of the mouth of the associated bottle for severing a stream of viscid liquid poured from the bottle and eliminating drip or running of the liquid downwardly of the bottle neck when the pouring is terminated; which is movable substantially into the mouth of the bottle so that a closure cap can be applied to the bottle without interference with the pouring spout; which is effectively sealed to the inner surface of the associated bottle neck; and which is simple and durable in construction, economical to manufacture, effective in use, and neat and attractive in appearance.

Other objects and advantages will become apparent from a consideration of the following description and the appended claims in conjunction with the accompanying drawing wherein:

Figure l is a face elevational view of a bottle with a portion broken away and shown in cross section to illustrate the position of a pouring spout, illustrative of the invention, in the neck of the bottle;

Figure 2 is a fragmentary top plan view on an enlarged scale of the bottle and pouring spout;

Figure 3 is a fragmentary cross sectional view on the line 3--3 of Figure 2; I

Figure 4 is a cross sectional view similar to Figure 3 with the bottle in pouring position;

Figure 5 is a fragmentary cross sectional view similar to Figure 3 but showing a somewhat modified form of pouring spout; and

Figure 6 is a perspective view of the pouring spout illustrated in Figure 5.

With continued reference to the drawing, the bottle, generally indicated at 10, has a neck 11 terminating at its outer end in a bottle mouth 12 and provided on its outer surface with locking ribs or screw thread formations 13. The outer end of the bottle neck is receivable in a cup shaped closure cap 15 the side wall of which is provided with formations 16 engageable with the rib formations 13 on the outer surface of the bottle neck to secure the cap on the bottle neck in closing relationship to the mouth 12 of the bottle. An annular bead formation 17 surrounds the bottle neck 11 intermediate the length of the neck and engages the open end of the cap 15 to limit movement of the bottle neck inwardly of the cap.

As the bottle and the closure cap therefore may be of a form well known to the art, a more detailed illustration of the bottle and the associated closure cap is considered unnecessary for the purposes of the present disclosure.

A pouring spout, generally indicated at 18, is removably disposed in the neck 11 of the bottle and includes a thin walled, hollow portion 20 of cylindrical shape having an outside diameter materially less than the inside diameter of the bottle neck and a thin walled portion 21 of truncated conical shape joined at its smaller end to the end of the portion 20 nearest the mouth 12 of the bottle and flaring outwardly from the portion 20 over the mouth 12 at the outer end of the bottle neck 11. The conical portion 21 of the pouring spout has a diameter substantially equal to the maximum diameter of the bottle mouth and is provided with a sharp outer edge 22. A sealing ring 24 of a suitable, elastic material, such as cork or a natural or synthetic rubber, surrounds the cylindrical portion 20 of the pouring spout near the end of this portion remote from the portion 21 and bears against the inner surface of the associated bottle neck 11 to provide a liquid type seal between the bottle neck and the pouring spout at the end of the pouring spout disposed inwardly of the bottle neck.

When the pouring spout 18 is in its fully retracted position, as illustrated in Figure 1, the larger end of the spout is contiguous to the mouth of the bottle and the closure cap 15 can be applied to the outer end of the bottle neck without interference with the pouring spout and will simultaneously close the adjacent end of the pouring spout and the mouth of the bottle.

When a viscid liquid, such as table syrup, is to be poured from the bottle 10, the closure cap 15 is first removed and the larger end of the pouring spout 18 is grasped between the finger tips and the pouring spout is pulled outwardly of the bottle neck and tilted to one side, as illustrated in Figures 2, 3, and 4. The sealing ring 24 is retained in position relative to the pouring spout by an outwardly projecting, annular flange 26 on the end of the cylindrical portion 20 of the pouring spout remote from the conical portion 21 thereof and slides outwardly of the bottle neck 11 as the pouring spout is pulled outwardly of the associated bottle neck. Movement of the pouring spout outwardly of the bottle neck is terminated when the conical portion 21 of the spout is disposed substantially entirely outwardly of the mouth 12 of the bottle and the spout is then tipped or tilted until its outer surface engages a portion of the bottle mouth, as is particularly shown in Figure 3. The bottle with the extended spout therein is then tilted, as illustrated in Figure 4, until liquid flows from the bottle through the pouring spout and out of the larger end of the spout. The liquid will pour from the larger end or rim of the pouring spout and, when a desired quantity of liquid has been poured from the bottle, the bottle is uprighted and the sharp edge at the rim of the spout quickly severs the viscid liquid, eliminating any drip and preventing any of the Liquid from running downwardly along the neck of the ottle.

After the bottle has been uprighted the pouring spout is pushed downwardly into the bottle neck to its retracted position and the closure cap may then be reapplied to the bottle neck without interference with the pouring spout.

As stated above, the pouring spout is a thin Walled body and may be formed of any suitable material although a synthetic resin plastic material is preferred.

In the modified arrangement illustrated in Figures 5 and 6 the construction is the same as that illustrated in Figures 1 to 4 inclusive and explained above except that two or more leaf springs, as indicated at 30 and 31 are secured to the pouring spout for automatically moving the spout outwardly of the associated bottle neck when the corresponding closure cap is removed. The leaf springs 30 and 31 extend longitudinally of the cylindrical portion 20 of the spout to the end of this portion joined to the conical portion 21 of the spout and at this location are bent outwardly to provide angularly disposed legs or portions, as indicated at 32 and 33, which overlie the mouth of the bottle. When the springs 30 and 31 are in their normal, angular shape, as is illustrated in full lines in Figure 5, the pouring spout is held outwardly of the associated bottle neck 12 a distance suificient to prevent any drip or running of the liquid when the associated bottle is uprighted after having been turned to pouring position. When it is desired to close the mouth of the bottle the closure cap 15 is placed over the larger end of the spout and forced inwardly of the bottle neck until it engages the rib formation 13 and is then turned down to its bottle closing position, as illustrated in Figure 1. This forces the spout 10 inwardly of the bottle neck bending the springs 30 and 31 toward a straight condition, as illustrated in broken lines in Figure 5, and causing the legs 32 and 33 of the springs to press outwardly and downwardly on the mouth of the bottle. As soon as the closure cap is removed the springs 30 and 31 will again force the spout outwardly of the bottle neck, sliding the packing ring 24 along the inner surface of the bottle neck for the corresponding distance.

It will be noted that the larger end of the pouring spout is of sufiicient diameter that it will not pass into the interior of the bottle neck 11 so that there is no danger of forcing the pouring spout into the bottle neck to a location at which the springs will not move it outwardly of the bottle neck when the closure cap is removed from the bottle.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are, therefore, intended to be embraced therein.
